Dry chlorine gas contains acid, how to solve it
Thread Content
Liquid chlorine filling, vacuuming systems, and pipes are often clogged with acid sludge. What is the reason? How to solve it? Please analyze the reasons. The picture is of the vacuum pump inlet pipe (please ignore the background of the picture and the shape of the acid mud:lol:lol:lol).
It is caused by problems with the water demister and acid demister. The white substance is sodium chloride.
What the poster is talking about is the liquid chlorine filling and vacuuming system, which has nothing to do with the main chlorine system.
It seems that the on-site equipment is severely corroded!
The negative pressure system should be a Nash pump that uses sulfuric acid for drying. The basic reason is that there is negative pressure in the pipeline during operation, and there is no problem at this time. The problem lies in the fact that after the Nash pump is stopped, the pipeline is still under negative pressure, gradually sucking in the concentrated sulfuric acid. It became like this after a long time. These are the same things in the concentrated sulfuric acid separator of the Nash pump. Solution: A one-way valve is added to the inlet of the Nash pump to prevent back suction after the pump is stopped. For double assurance, the inlet manual valve is closed after the pump is stopped.
This happens to us too and we have to clean it every half month.
Check the sulfuric acid concentration~~, perform a pressure test on the vacuum system to see if there is any leakage, and suck water from the air into the system~~
You can check whether there is any problem with the liquid seal under the acid mist trap.
The purity of the high-concentration sulfuric acid used is very important. Whether it is sulfuric acid with few impurities, check whether the system is leaking, and then check the mist removal effect of the acid mist trap.
